This is a print I designed to keep multiple push buttons together. The intended use was actually for training our dog. Each pad holds three buttons but you can connect as many pads together as you like. I designed it to be used with the push buttons on the following link:

There is a cutout to keep the reset button from being pressed, so make sure the push button is inserted with the correct orientation.

There is a connector file to put two boards together as well as a file to fill the connector cutout when you don't want to connect another board.
